"We had just purchased our home and after a few days found that the septic system was having a problem - it smelled terribly. A septic contract was a required part of the purchase, however, after 2 months that company was making no headway in getting it fixed and we were unhappy and our neighbors were becoming annoyed with the smell too (understandably so.) We decided to try Total Septic upon recommendation of another neighbor. They were able to schedule our service for the next day. After a few minutes diagnostics, their technician felt confident he knew the issue and went to go get parts. That same afternoon, he replaced the air pump and verified aeration of the tank and explained it would take about 4-7 days to clear the smell. It did and we are extremely happy. I'm not the greatest fan of "star" ratings, but to explain my own below: 1) Work Quality 4.5/5, could it have been better (how it was mounted, setup, etc, yes, but for the price, I think they did a great job and anything more, probably would have required more time and more planning, nonetheless, those options weren't presented, so as close to a '5' as you can get. 2) Customer Service - Absolutely a '5' - Hands down excellent. They did not require a bunch of coordination or paperwork before coming out, they just made the appointment and fixed the problem asking for payment immediately after. We also chose to sign a support contract with them so we can continue to enjoy their excellent service. 3) Value for the money - I had priced replacement pumps and thought that was the problem, but I would be taking a gamble that my uneducated diagnosis from internet information was wrong. I received expert service and experience as well as same-day replacement for nearly the same price. In summary, I could not be happier with the service and people at Total Septic!"

"I specified that it was a tankless water heater, yet not surprisingly I was referred to a plumber who didn't know anything about tankless heaters, resulting in a waste of a couple of days. The second person did know about them, and so far the repair is working (fingers crossed). I wish CHW would pay attention to the details in my claim."

"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

Septic Tanks FAQs, answered by experts

There are a lot of issues that can cause a septic tank to collapse. Those include failing to regularly pump or service it every three to five years, placing too much weight atop the system—by parking your car on top of it or because of a heavy snow buildup for instance—or because of structural damage done by overgrown tree roots.

Many contractors offer warranties for parts and labor. Confirm terms before hiring.

If you aren’t sure if you have a septic tank or a cesspit, you can check your property records or inspect your drainage system. A septic tank has an outlet pipe that allows liquid to drain into a soakaway or drain field, while a cesspit is a sealed tank that requires frequent emptying. If you notice a manhole cover and no nearby drainage field, it’s likely a cesspit. Signs like slow drainage or a frequent need for pumping can also provide clues. A professional inspection is the easiest way to confirm if your home runs on a septic tank or cesspit.

How to size a well pressure tank is determined by three factors: flow rate, or how many gallons per minute your well pump produces; minimum runtime; and pressure switch setting. Most pressure tanks have a pressure switch operating at 20/40, 30/50, and 40/60—the first number is the pressure needed for the pump to turn on, and the second number is the pressure needed for the pump to switch off. Most homeowners relying on well water require a water pressure tank ranging from 20 to 80 gallons. 

Conventional anaerobic septic systems are the most cost-effective and least expensive type, with installation costs typically ranging from $3,000 to $8,000. For comparison, sand filter systems cost between $7,000 and $18,000, while mound systems are the most expensive at $10,000 to $20,000. Several factors influence the final price. The tank material is a key consideration; plastic tanks are the most budget-friendly option, starting around $2,900, but concrete and fiberglass tanks offer greater durability and longer life spans at a higher cost. The size of the tank also affects the price. For example, a 1,000-gallon tank costs between $900 and $1,500, whereas a larger 1,500-gallon tank costs $1,500 to $2,500.
